Ping when cold

[airline tech]

Its looks like they revised the manual, since that was posted.
FYI- The revised P/N for the plugs is SP-594, the SP-578 was discontinued (from the manual you posted)

The Part # you have installed = CYFS-12YRT3 - Crosses to SP-594, which matches the owner's manual as well.

The plugs look normal but also look like slight octane fouling, IDK it's your call, I would most likely just replace them and see how it does, but again we share the same Midwest weather so its warming up now. (Finally)
Just curious are you in the KC area? I am on the KS side of the river.

Plugs look fine. At some point you will have to accept there is nothing wrong and there is probably a point in the programming that is causing it. Either necessary for emissions or just a slight programming error. It would be interesting to see what a Ford tune would do to it.

Yeah, I'm out in Lee's Summit, work out in Lenexa. This is why my data logging is so long

That was my conclusion as well just a little MMT staining. Going to let the seafoam do its job and go from there. May have to try to keep the rpms down below 2.5k until warm when temps are below 60.

Your probably right. Might switch back to 87 octane when it gets cold again and see what happens. But I think temps are going to stay above what I think is the threshold until fall now. So for now I'll just drive it and enjoy the truck.

Just curious if you read this thread, I just read it and it may relate to your issue. (Similar)
I have seen it before but never really read through it until today.

Bucking/Surging Epidemic | 2019+ Ford Ranger and Raptor Forum (5th Generation) - Ranger5G.com

Further Investigation hopefully will reveal something on that thread, other than just replacing parts.
The only reason I am bringing it up, is it's a no code issue and what might be a Buck Surge feel to some might be described as a Spark Knock as well.
What caught my attention was some but not all of the posts originated with cold temps by their posting date.
So, I am thinking its more related to not the Temps but is it a cool dewy morning with high moisture content in the air.

One poster noted cylinder 1 & 4 plugs being burned. (Noted Point) and ironically similar.

Remember seeing the thread but never really looked into it I'll check it out. 26 pages looks like I'm going to busy reading for awhile. Sounds like it should be interesting to say the least. Since our 90* day is coming to an end, I can sit on the deck enjoy the evening and reading.

@ airline tech
Well I'm still just poking around online to see what I can find out on how all this new tech works and came across this. It say 19 but the revision is 17, so I don't know that I could trust the values, but theory and operation might be sound.

 

[seasprite]

Well that didn't post like I thought it would.
What I think I found out, maybe any way. The noisy fuel pump might be from double injection?
And if the High pressure fuel rail sensor goes bad by reporting the wrong pressure with in spec it can lead to lean or rich conditions visible only with your fuel trim pids.

After reading all this hooplah my conclusion is what you are hearing is normal and to just drive the truck

For reference, I definitely had a sound on the Livernois 91-93 performance tune that was not there stock. After talking to them and doing data logging everything checked out fine. But I still didn't like the sound. Switched to the towing tune and ended up liking it a lot (felt safer and more refined) and happened to buy a trailer later that year. No sound and no problems so far with clean Blackstone reports on Motorcraft fluids/filters. What may have helped is going to the colder plugs and splash blending some E85 each tank, which continue to do. But to each their own, that's just my story

The ping or knock is gone for now due to weather temps being above 60* or the seafoam that that I currently running in the tank and I don't think its normal.
The extra noisy fuel pump for about a minute or so then quiets down to a normal noise level is normal due to a strategy to heat the cats up faster.

I'm coming from 2005 tech so I have a lot to catch up on my last post is basically me learning about these new systems and how they operate. I was able to take my 5.4 3v engine to 245k and 17 years without hardly an issue due to learning about the engine. The only thing I replaced proactively on it was the injectors due to a chance of hydro locking the engine for that year. I did switch oil weight to 5w-30 instead of 5-20 for that engine to which helped extend the life of the roller followers that had started to make noise when I traded it in.

So this isn't hoopla its a learning process and after working on ford motors for 30 years I think I can figure out what is normal and not. With the help of other forum members the process can be expedited and I thank them for that.

Oh and my engine is stock no tune. I like to keep it stock for longevity reasons and if I do have to take it in the shop for something the techs know what there dealing with.

Five pages later and haven't gotten anywhere

Make sure to check your dipstick and post on the fuel in oil thread too

 

[airline tech]

Well today, I decided I would pinpoint the noise I hear when opening the driver's door, what I thought all this time was the HP Fuel Pump is actually the Wastegate actuator.
So, I learned something new today.

I feel you are correct about it just being a programming issue, be it normal or not. A new truck should not normally ping.
Being this is a No-Code issue, I just thought something might stand out in the PID Data, but so far it is a bust.
I do not feel it a waste of time to attempt to help another forum member, as it forces me to dig deeper in learning Fords, I have been a GM owner most of my life and now proudly own a Ford, being that I walked away from automotive maintenance and crossed over to aircraft years ago, a lot has changed since then.
I have rebuilt a couple of motors but have never tuned as I walked away before Turbo's became a norm along with Scan tools.

Did find a little soot in the tail pipe, don't know why I didn't check this earlier. But I think @Rp930 may have hit the nail on the head with the carbon build up in the cylinders. Don't think its doing this anymore or we would of seen it in the fuel trims. So my plan is to run a few tanks of cleaner through engine to clean things up and see if that does the job.
Like you guy's have said nothing is showing up in data and plugs are clean, so its programing or carbon in the cylinders.
@airline tech yeah its going to be interesting learning about all the new tech that is on these engines.
Thanks to both of you for helping, that's what I love about these forums
The truck is not pinging for now, so either the temps are warm enough or the seafoam is having an effect.
We'll call this solved for now and if anything changes I'll update the thread.

I would make a suggestion. Use Techron (a proven winner for deposits). It was used by several makes in the old days and it does work. I just don’t have any real experience with Seafoam.

And another caution: Don’t over use any cleaner. The manufacturer told you to fill up, put in a bottle of Techron, run it down to 1/2 tank, fill up and put in another bottle and run to empty. It was advised to change oil afterwards because those deposits can end up in the oil. If it seems to cure your issue I would switch to a Top Tier gas station and forget the non ethanol you’ve been using. Good luck.
